Pearlyond Technologies Singapore is an ISO9001 certified fiber optic patch cord cable manufacturer and fiber optic test equipment manufacturer since 2001,We supply OEM fiber optic products to world leading companies, our products include fiber optic patch cord,adapter,fiber optic attenuator. ic system. Fiber optic testing of a newly installed system not only verifies that the system meets its design requirements, but also creates a performance baseline for all future testing and troubleshooting of t at system. Corning recommends that all fiber optic systems be tested to a minimum set. er classes and connector combinations to cover all necessary requirements. Each cable is single packed in a polybag with a test report that guarantees best performance in typical application scenarios like telec This standard is a modified adoption of the British Standard BS 6387:2013 (Test method for resistance to fire of cables required to maintain circuit integrity under fire conditions) to the national requirements and the particular needs of the local industry. FMS-400 fiber inspection microscope has 400xmagnification, a focus wheel, and features 2. 25 mm (LC) adapters for use onmost fiber connectors.
